Sea-level rise

In regions where land is steadily rising relative to mean sea level, the effects of sea-level fluctuations are sometimes recorded as ero-sional features on land. Whenever the rate of sea-level rise matches the rate of uplift, there is an apparent sea level still stand. Both deposition and erosion are controlled by this almost fixed base level, and a terrace may form. If sea level falls and again rises, the terrace will have risen sufficiently so that it is preserved upslope. Epi-... 

The combined data (Fig. 16) show that sea level reached a minimum during the LGM between 20 and 22 ky ago. The rate of subsequent sea level rise was not constant, with relatively rapid rise (melt water pulses) at about 19 ky, between 15 and 14 ky and at about 11 ky, with intervals of little or no rise in sea level immediately before each of these pulses. The latter two of these low sea level rise-melt water pulse pairs correspond...

Box 1. Potential change of sulfur biogeochemical cycle in Thai Mangrove ecosystems due to sea level rise resulting from climate change scenarios (after Bashkin, 2003a Rummasak et al., 2002)... 

Increasing concentration of GHG in the atmosphere will lead to climate change and the most probable scenarios are related to sea level rise. According to these scenarios the mangrove ecosystems of the South East Asia and Thailand coast, in particular, will change many features, especially those connected with the biogeochemical cycle of sulfur.

The choice of different targets is not only relevant because it leads to different uncertainty ranges, but also because it leads to different strategies. Stabilisation of one type of target, such as temperature, does not imply stabilisation of other possible targets, such as sea-level rise, radiative forcing, concentrations or emissions. 

In the event of a decline in sea level, the supratidal zone will move seaward, causing evaporites to deposit on top of old lagoonal sediments. When sea level rises back, it drowns these evaporites. These low-amplitude fluctuations in sea level build up laminated sediments in which layers of biogenic oozes and organic-rich muds alternate with evaporites. 

Computer models have been developed to predict the effects of the forcing fiuic-tions shown in Figure 25.22 on future climate change and sea level rise under a variety of what-iT scenarios. A recent set of projections based on several likely GHG emission scenarios is presented in Figure 25.23. In 1990, the IPCC presented a first set of projections, estimating that between 1990 and 2005, global average temperatures would...

Sea level rise. With increasing surface temperatures the average sea level will rise because of three factors melting of polar ice caps, receding of glaciers, and thermal expansion of the ocean surface waters. Combining all three factors,...
